Be it known that I, BELA GEREBEN, a sub- 1 the main frame andS is acoiled spring the ject of the King of Austria-I-Iungary, residing endsof which are secured respectivelyto-the at Budapest, in the Kingdom ofAustrial spindle l and the adjacent bracket 2: 011 Hungary, haveinvented certain new and l' the spindle 1 is secured a?si1iglc'piecegraduuseful Improvements in 'labulators for l i Type-'Writers; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to a tabulator device for typewriters.

The essential feature of my invention consists in providing a rotatinggraduated stop cooperating with the tabular stops, means being providedfor turning and fixing the said rotating stop in its different positionsand means being provided to actuate the cardial steps 5.' The distancefrom each step to the next corresponds with the space of the letters ofthe typewriter, and with the carriage-feeding movements. On thespind'le1 a sleeve'6 is loosely mounted to turn freely relatively to saidspindle. From the said sleeve a lever 7extends (lownwardly the end ofwhich is bent outwardly at a right angle. A substantiallyhorizontalthumb 8 projects backward from sleeve 6 and rests on the well wardprojecting arm'lO of the sleeve 6 bears the brake plate 11 covered withleather or the like and acting against the flat brake-bar 12 mounted onthe carriage.

Further means may be provided to allow the tabular stops to yield in thedirection permitting to turn the rotating stop when adjacent to one ofsaid tabular stops.

My invention aims also to improve the brake acting on the carriage, whenthis latter is released on the working of the tabulator.

The scope of my invention will be more fully described and claimedhereinafter.

In the accompanying drawing, which illus trates an embodiment of myinvention applied on the machine-type known under the name Underwood,Figure 1 is a rear elevation of the upper part of the machine providedwith the tabulator. For the sake of clearness several details of thetypewriter are omitted. Fig. 2 is aside elevation of the tabulatordevice with the adjacent parts of the typewriter. Fig. 3 shows the crosssection of the oscillating stop rod with the tabular stop when yieldingon the action of the rotating graduated stop. Fig. 4 is the front Viewof the tabular knob with the dial or tabular scale. Fig. 5'showsdiagrammatically the improved wedge shaped brake bar in plan view. Fig.6 shows a modified form of the rotating graduated stop. Fig. 7 shows thepreferred form of finger piece for setting the wedge shaped so that theacting face of said bar is slightly divergent to thepathofthe carriage,the braking effect increasiiigE thus toward the end of the travel of thecarriage.

B and supporting-the toothed taliul'ar'stop rod 14, the. ends of whichare pivoted in said bracketslB. l A spring fastenedwith its endsrespectively to the tabular stop rod 14 and to the left bracket 13 actsto return the .rod 14 in its normal position shown in Fig. 2 when it wasturned in the'position Fig. 3. On the brackets 13 abutments 16 may be.formed (see also Fig. 3) fixing the normal position (Fig. 2) of the stopbar. I

The spindle 1 supports near its left end a bevel mien 17 fixed theretoand meshing with the pinion 18 supported by a vertical shaft 19journaled in bearings 20,21. secured to the main frame A. Tothe lowerend of the shaft 19 is fixed the bevel pinion 22 meshing with a pinion23. The bevel pinion 23 is secured by means of its hub 24, on ahorizontal spindle 27 to rotate together with said spindle but to allowa longitudinal shifting of the spindle in the hub of the pinion. Thespindle 27 is journaled in the bearings 25 and denomination stops. Y

A is the main frame of the machine and B is the carriage. Both are oithe well known construction.

bracket 26 to the bearing 2]. and. the latter secured to the main frameA. The frontend ated stop 4 provided with a plurality of raknowncarriage releasing lever fi. f Aii up'-.

As shown in Fig. 5, the bar 12 is slightly 7 13, 13 are brackets securedto the carriage 28, the former attached by means-oi the of the spindle27 is provided with a knob 29 having a recess with roughened surfaceadapted to receive the thumb of the operator when turning the knob. Y

On the main frame A is secured a dial 31 and on the part of the spindle27 between the frame and the knob a pointer 32.

A rin'g'33 forming a shoulder is fixed to the spindle 27 and a spring 34is located between the bearing 25 and the shoulder 33 securedrespectively to said bearing and shoulder. When the knob 29 is turned orpushed the spring 34 is stretched or compressed and will return afterthe knob is. released this latter together with the spindle 27 in theinitial position.

The spindle 27 is fitted with a disk toothed on its periphery, the teethcorresponding withthe scale of the dial 31. On a support secured to themain frame a pin 36 extending toward the toothed disk 35 is arranged toenter the corresponding recess betweenthe teeth of the disk 35 when thislatter is approached to the pin 36 by pushing the knob 29.

The device operates in the following manner: When a number of fourfigures for instance shouldbe written, theknob 29 is' turned until thepointer reaches number 1000 on the dial. The knob is then pressed in,whereby the position of the knob and the spindle 27 is secured fromrotation by the pin 36 entering the recess of the disk 35 being in frontof the pin 36. The pin 36 and the recesses of the disk 35 may be wedgeshaped or tapered to facilitate the operation. By turning the knob 29,the spindle 27 is rotated and the movement of this spindle istransmitted by means of-the bevel pinions 23, 22, the shaft 19 and thepinions 18, 17 to the spindle 1, turning thus the graduated stop 4 withan angle corresponding to five steps on the stop 4, because 1,000corresponds to the fifth degree of the scale of the dial. By ushing theknob inwardly, the spindle is shifted longitudinally in the hub of thepinion 23 without altering the position of this latter fixed by the pin36 engaging the disk 35.

The end of the spindle 27 is disposed in front of the bent end ofthe arm7 so that on shifting the spindle 27, the lever 7 and the sleeve 6 isslightly turned-on the spindle 1..

Thereby on the one hand the thumb 8 depresses the carriage releasinglever 9 and is pressing on the other hand by means of the arm 10 thebrake plate 11 against the brake bar 12. The carriage thus released willjump until the stop 37 mounted adjustably on the tabular stop rod 14willabut against the fifth step 5 of thegraduated stop 4 brought byhaving turned, the knob 29 into the path of the tabular stops 37, 38.The movementof the carriage is lgpverned by the action of the brake 11,12 w ch increases toward the and of the travel of the carriage owing tothe wedge shape of the bar 12. The knob 29 is then released by theoperator, whereupon the parts are brought by means of the springs 3 and34 in their original position. The pressure exerted on the carriagerelease lever 9 ceasing, the escapement of the carriage, which isdesignated by C is put in action and stops the carriage in the positiondetermined by the stop 37 and by the fifth step of the rotary stop 4.

If a number of five figures should be written, the rotary stop willbemoved so far, that the sixth step is turned into the path of the tabularstop 37 of the carriage and if a number of three figures must be writtenin the column of numbers, the rotary stop 4 will'be turned so that thefourth step may extend into the path of thestop 37, and so on.

It will be understood that the operator must maintain pressure upon thefinger-piece 30 until the carriage is arrested by the stops, and thatthe tooth 36 is intended merely to lock the shaft 27 against rotation.

When the carriage is stopped by the mutual action of the stops 4 and 38,the operator releases. the knob 29, and the stop 4 rotates to normalposition. immediately turned again without first Writing anything, therotary stop 4 can easily be turned by said knob, to any desired point,in spite of the fact that stop 38 is in front of the stop 4 (see Fig.2). '1 he stop 4 abutting against the stop 38 tilts the stop and thepivoted rod 14- (Fig. 3) until 4 can pass by 38-. In other words, by therotation of the stop 4, the column stop 38 can be turned out of the way,effecting a rotation of the bar upon which the stop 38 is mounted. Thecarriage may then be released and then arrested by the engagement of thenext column stop with the selected stepped shoulder on stop 4.

It will be seen, that the stops 37, 38 limit the travel of the carriage,but do not hinder the rotationof the graduated stop 4.

It will be understood, that the details of myinvention may be varied indifferent ways without departing from the scope of my invention. Thusthe helicoidal graduated stop 4 need not always be provided with stepsbut can be formed as a continuous helical surface, as shown in Fig. 6and the tabu lar stops arran ed 'on the rod 14 may be fitted withsimilarly formed oblique faces. Instead of the knob shown in Fig. 4the-knob shown in Fig. 7 may be used, which is provided with a wing 39-for turning the knob by means of the index, while the thumb resting Ifnow the knob 29 is on the knob 40 seryes for pushing in this lat?
